Edgeworth's conjecture

When the number of agents in an economy increases, the degree of indeterminacy is reduced. In the limit case of an infinite number of agents (perfect competition), contract becomes fully determinate and identical to the 'equilibrium' of economists. The only way of resolving this indeterminacy of contract would be to appeal to theutilitarian

Taxation paradox

Taxation of a good may actually result in a decrease in price. He set the utilitarian foundations for highly progressive taxation, arguing that the optimal distribution of taxes should be such that 'the marginal disutility incurred by each taxpayer should be the same' (Edgeworth, 1897).Monopoly pricing

In 1897, in an article on monopoly pricing, Edgeworth criticised Cournot's exact solution to theduopoly

Edgeworth's limit theorem

Edgeworth's limit theorem relates to equilibrium of supply and demand in a free market. See Edgeworth's limit theorem. Though Edgeworth's economic ideas were original and in depth, his contemporaries frequently complained of his manner of expression for lack of clarity. He was prone toverbosity
